Abstract: In  method  for  manufacturing  electrode,  the  method   is charactered by  pre-treating  aluminum  foil  by  12.6  wt.%  NaOH solution added with 0.2-0.8 wt.% sodium  silicate  before  etching it. In this method, when content of sodium silicate is at most 0.2 wt.%, the penetration of NaOH to aluminum metal becomes easy,  and number of corrosion initiation point is not enough.  When  content of sodium  silicate  is  at  least  0.8  wt.%,  the  electrostatic capacity of aluminum decreases, and etching time becomes long.  It has advantages of increasing electrostatic  capacity  of  aluminum and etching efficiency.

Abstract: PURPOSE: A fabrication method of a thin film transistor is provided to simplify a fabrication process of a thin film transistor by forming an etch stopper layer and an amorphous silicon layer simultaneously using a photo etch process, thereby enhancing a yield and a characterize of the thin film transistor. CONSTITUTION: A gate electrode(2) is formed on a transparent substrate(1). A gate insulating layer(3), a semiconductor layer(4), an etch stopper layer(5) and a photoresist layer are deposited sequentially on the substrate in which the gate electrode is formed. After patterning the photoresist layer by a back exposure using the gate electrode as a mask, the etch stopper layer(5) and the semiconductor layer(4) are taper etched at same time and the semiconductor layer is patterned in a narrower width than the gate electrode. After depositing an impurity semiconductor layer(6) and a metal on an entire surface and annealing thereof, the impurity semiconductor layer and the metal is removed selectively, a source/drain electrode(7,8) is formed.

Title: Semiconductor chemical vapor deposition apparatus
Inventor: KIM SANG-YUP
IPC: H01L21/205
Filed: 1993-03-31
Granted: 2000-05-01
Abstract: PURPOSE: A semiconductor chemical vapor deposition apparatus is provided to obviate disturbance within a process chamber and stabilize the flow of gas by installing a buffer of a filtering mode and a multi-layer structure. CONSTITUTION: A semiconductor chemical vapor deposition apparatus includes a chamber structure for realizing a laminar flow. The chamber structure includes a hole at the side of rings in a circular plate. A buffer being circular plate rings has an increased number of holes by making fine the hole as the rin directs from an inlet of a pump(7) toward an internal direction of a process chamber(9). The buffer is also installed at the side of the wall along the pumping path within the process chamber(9).

Title: Method or arrangement of measuring for fly waste of spinning yarn
Inventor: CHOE JIN-KOOK
IPC: D01H13/32
Filed: 1993-04-28
Granted: 1996-10-21
Abstract: The fly waste is mesured by falling off a floating fiber on the surface of yarn due to the centrifugal force by circular movement of yarn delivered through narrow yarn feeder from spun yarn cheese in a hermetically sealed space, consecutively going through and contact with the yarn passed into the sealed space on the surface of a multiple metal guide, removing a feather of the yarn by friction force between yarn and metal surface, and then measuring fly waste weight of the removed floating fiber and the feather in such a manner. In addition, the apparatus measuring the fly waste is disclosed.
